Summary Verdict
The 2011 Chrysler 300 is a generally reliable vehicle, particularly with its powertrain options. The 8-speed automatic transmission is notably robust. However, owners should be aware of potential issues with the 5-speed automatic, especially concerning shifting quality. Engine-wise, the Pentastar V6 can experience intake manifold and oil cooler leaks, while the HEMI V8 might face oil pressure sensor or exhaust manifold problems. Electrical gremlins related to the Body Control Module and premature alternator failure are also documented concerns. Suspension components like ball joints can wear over time, leading to noise and handling issues. While interior and exterior elements are largely sound, headlight condensation and infotainment screen unresponsiveness are occasional complaints. Regular maintenance and prompt attention to early symptoms can mitigate many of these potential reliability concerns.
